MNS Power brings you the SPG-R300W stationary power generator bolt on kit.

Please note: this is JUST THE BOLT ON KIT. You will need to spend $250 and purchase your own Sunny Indoor Cycling Bike from Amazon or Craigslist.com. This system is more efficient than the belt drive system and the roller system because it has less friction between the roller and the wheel.
